SPRINKLER TOP FOR CONTAINERS.

Application filed January 18., 1926.1 Serial No. 82,046.

This invention relates to certain improvements upon the sprinkler top for containers set forth in the patent granted to ine on the 23rd day of November, 1915, No. 1,161,? 18.

The object of the present invention is to so design the top that the sliding valve will be held tightly to its seat at all times, and to dispense with holding means projecting through the valve, substituting therefor a ring comiected to the spring members of the valve. The invention also relates to certain details of construction described here-v inafter.

In the accompanying drawing Fig. 'l-is a perspective view of a container showing the improved sprinkler-top;

Fig. 2 is a plan view;

Fig. 3 is a side view;

Fig. 4 is a vertical sectional view on the line 4-4, Fig. 2, showing a packing disk;

Fi 5 is a side view partly in section on the line 5-5, Fig. 2, showing the valve in the open position.

Fig. 6 is a perspective view of the packing disk; and

Fig. 7 is a sectional view similar to Fig. 4, in which the valve and its seat'is omitted.

The body 1 of the container can be of any form desired. The cap 2 has 'a deep flange in the present instance, and projecting from the cap is a tubularyextension 3, forming a valve seat. In the valve seat are perforations 4.

1 A valve 5 is mounted on the valve seat at the end of the projection, and-in the valve are perforations 6 which are arranged to align with the perforations 4 in the seat when moved to one side, as in Fig. 5.

- When the valve 5 is in its normal position, the solid portions of the valve close the perforations 4 in the seat, preventing the escape of the contents of the container.

The valve is in the form of a flat sheet metal plate. In order to prevent the valve turning on its seat, a rib 7 is formed on the seat, and the valve isgrooved as at 8 by pressing the metal toreceive the rib, so that while the capcan slide freely in one direction, it cannot turn.

At opposite sides of the valve'5 are tongues 9, which are shaped to form springs. These tongues are connected to a rin 10. The tupacking disk between the formed therein to receive-the ring 10. The upper wall of the groove forms a shoulder,

retaining the ring in position and holding the valve close to its seat, and the springtongues fulcrum at the ring, so that when either tongue is pushed, as indicated by the arrow, Fig. 5, both tongues yield, allowing the valve to move to one side and uncover the perforations 4 in the seat. As soon as the valve is released, the spring-tongues return thevalve to its normal closed position.

The valve ring and spring-tongues are preferably made integral either by forming a cup-shaped blank and cutting the parts by suitable dies, or by stamping the parts flat and then bending them to shape, the end of the blank forming the ring being connected after being applied to the extension of the cap. A packing disk 12 is preferably located between the valve and its seat, as shown in Fi 4, the seat being depressed to receive the disk, which is shaped as shown in Fig' a perforated seat and having an annular groove some distance below the seat; a perforated valve arranged to slide on said seat:

=a retaining ring located in the groove; and

a spring-tongue connecting the ring with the valve.

2. The combination of a container having an extension provided with a perforated seat and having an annular groovesome distance from the seat; a perforated valve mounted on the seat; a ring located in the groove; and two spring-tongues connecting the valve to the ring.

3. The combination of a container; an extension thereon having a shoulder; a perforated valve seat at the end of the extension; a perforated valve mounted on the seat; a ring encircling the extension and bearing against the shoulder; oppositely disposed spring-tongues connecting the valve to the ring; and means for preventing thevalve turning on the seat, the perforations in the valve being out of line with those on the seat when the valve is in its normal position.

4. The combination of a container having Q Leon-nee pressed; a packing disk located in the decentre} transverse guiding rib formed there- 30 pression and having perforations aligning on; and a perforated valve mounted to slide with those in the seat; means for preventing on said seat and havin a, groove to receive the packing disk from turningyand a pen the rib, so that the va ve is guided by the v 5 foratcd valve mounted on the end of the rib the valve having a s ring-tongue, said container and having spring tongues attongue being attached to t e container some 15 tacked at their ends to the container. distance. from the seat.
